Summary
Completed in 1938, this earth dam spans 530 feet and has a storage capacity of 110 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes to ensure its safety and compliance with state regulations.
Situated on TR-SPRINGCREEK, Sd Noname 102 is managed by a private owner and falls under the jurisdiction of the state of South Dakota. Although the dam's condition assessment is currently not rated, its emergency action plan (EAP) status and risk management measures are not fully documented. Despite its age, the dam poses a low risk to surrounding areas and has not undergone significant modifications in recent years. As an important infrastructure for water resource management, Sd Noname 102 plays a crucial role in maintaining water storage levels and regulating water discharge in the region.
With its historical significance dating back to the late 1930s, Sd Noname 102 stands as a testament to the engineering and construction practices of its time. As climate change continues to impact water resources and infrastructure around the world, the monitoring and maintenance of dams like Sd Noname 102 become increasingly important. By staying informed about its condition, regulatory oversight, and emergency preparedness, water resource and climate enthusiasts can contribute to the preservation and sustainability of this essential piece of South Dakota's water management infrastructure.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
